Unable to take screenshots in headless mode

[port-eighty]

What is your Scenario?

Take screenshots on failed tests with quarantine mode in chrome:headless or edge headless.

What is the Current behavior?

When running on chrome:headless, screenshots do not work

What is the Expected behavior?

On test fails it will re-try until attempt limit and take screenshots at each run.

What is your public website URL? (or attach your complete example)

www.google.com

What is your TestCafe test code?

test.js:

fixture.only(`Test`).page(`www.google.com`)

test.only(`Test screenshot headless`, async t => {
	await t.wait(2)
	await t.expect(false).ok(`This is a test`)})

test.only(`Test screenshot headless`, async t => {
	await t.wait(2)
	await t.expect(false).ok(`This is a test`)})
	
test.only(`Test screenshot headless`, async t => {
	await t.wait(2)
	await t.expect(false).ok(`This is a test`)})
	
test.only(`Test screenshot headless`, async t => {
	await t.wait(2)
	await t.expect(false).ok(`This is a test`)})

This issue has been faced before but was supposed to be fixed (Link to #6886 comment )

[AlexKamaev]

I managed to reproduce the issue with NodeJS v18.7.0 and Windows 10. Thank you for reporting this. We'll research this issue. Until it is fixed, please use the stable NodeJS version.

Release v2.1.0-rc.1 addresses this.
